Professional associations - You can check the websites of professional associations, such as the American Institute of Certified Public Accountants (AICPA), to find a list of CPAs in your area. These associations usually have directories that you can search by location or area of expertise.

Online directories - There are several online directories that list CPAs in your area, such as the National Association of State Boards of Accountancy (NASBA) or the CPA Directory.

Search engines - You can use search engines like Google to find CPAs in your area. Simply search for "CPA near me" or "CPA [your city]" to get a list of local options.
